Claims27
A curable composition comprising:
- a resin component and a hardener component wherein the resin component comprises an acrylated urethane oligomer and a liquid epoxy resin, and the hardener component comprises an amine.
A curable composition comprising:
- a resin component and a hardener component;
- the resin component comprising an epoxy resin in amounts ranging from 15% to 40% of the total weight of the resin component, an acrylated urethane oligomer in amounts ranging from 2% to 15% of the total weight of the resin component, a flexible liquid epoxy resin in amounts ranging from 0.5% to 5% of the total weight of the resin component and a first filler in amounts ranging from 40% to 75% of the total weight of the resin component;
- the hardener component comprising a flexible amine in amounts ranging from 10% to 40% of the total weight of the hardener component, a curing agent in amounts ranging from 0.05% to 5% of the total weight of the hardener component, an accelerator in amounts ranging from 2% to 7.5% of the total weight of the hardener component and a second filler in amounts ranging from 40% to 75% of the total weight of the hardener component.
A process for making a cured material comprising the steps of:
- providing a resin component comprising an acrylated urethane oligomer and a liquid epoxy resin;
- providing a hardener component comprising an amine;
- mixing the resin component and the hardener component to obtain a curable composition;
- and
- incubating the curable composition at a temperature for a time sufficient for a cure reaction to occur.
